This is just a thought, but I did have problems with
eepro100 ethernet adapters with back level device
drivers, at one time. They broadcast two different
MAC addresses. They actually broadcast a real MAC
address the first time, but it comes time to configure
them, they broadcast a second, bogus MAC address which
is actually 6 random bytes of code, in memory. I
posted this problem to the eepro100 mailing list, and
Don Becker replied that the device driver was reading
the wrong location to get its MAC address the second
time -- I fixed the problem by having two entries for
each NIC in the /etc/dhcpd.conf file -- one for the
true MAC address, and one for the bogus one, with
identical IP information.
It has been a while since I debugged DHCP problems. I
suspect you can see the client broadcast its MAC, then
the master offers IP information, but you never see
the client configure its ethernet with the IP
information, is that correct? And then the client
fails at that point, yes?
